flanges 12 being arranged against the outer face of the Wall in suoli mannei as to cause the attached flange 13 to project over the adjacent edge of the Wall. Each side edge of each end ivall is provided with a pair of lthese, angled retaining plates 11 and the opposed ends of the anges 12 of each pair, are provided with a rolled finger hold 14 while secured to the outer face of the vWalls between the opposed ends of each pairwof members .11, is an arcuate spring member 15 secured to the outer side of the end wall by apiii or screw member 16 which passes through the central portion thereof 'and secures the member 15 with the ends dii'ectcd downwardly against the supporting wall body. Then the side ivall securing plate members 11 are drawn together, the portions 12 ride up upon the adjacent end of the spring member 15 as Will be hereinafter described.

The flanges 12 of each of the angled secur ing plates 11 are provided with a pair of arcuate slots 17 which slots extend from the inner or free edge of the plate in which they are formed toward that end upon which the finger hold 14 is formed. Extending through each of the slots 17 of each member 11 is a securing pin or groove 18 upon which the member rides. From the foregoing description it Will be readily seen that when the opposed ends of each pair of side Wall securing plates are drawn inwardly together they Will be caused to move in such manner as to shift the iange portions 13 outwardly away from the adjacent edge of the end Wall, and the inner end of each of the members Will ride upon the spring member 15. When the members 11 are returned to their position the locking spring la will bear against the inner ends of the members and maintain them in operative position.

The central partition 7 of the crate has each side edge provided with a plurality of headed pin members 19 which correspond in number to the key-hole slots 9 of an adjacent one of the side walls of the box and when the box is being assembled the partition 7 has a side wall secured to each side edge thereof by the extension of the members 19 through the key-hole slotshformed therein, the Wall being secured to the partition by moving it in such manner as to engage the heads of the members 19 over the constricted portions of the key-hole slot as will be readily understood.

When the box is being assembled all of the retaining plate members 11 are moved to the releasing position or in other Words each pair of members is drawn together to cause the flange portions 13 to move outwardly from the adjacent edge of the end wall carrying the members. Three of the side Walls can be fixed to the partition mem bers 7 in the manner described and then the end walls may be placed in position to cause the flange portions 13 of the members l1 to overlie one end of each of the side Walls. Each pair of retaining members 11 overlying each of the said side Walls may then be shifted to lo:king position and the flange portions 13 will bear against and frictionally hold the Walls in contact with the adjacent edges of the end walls. After filling the crate, the top wall can be slipped in position beneath the raised members 11 at each end of the open side of the box and after the members 19 have engaged in the key-hole slots 9 of the top then the members may be shifted to locking position in the manner de scribed.

From the foregoing, it will be readilyr seen that the box embodying this invention may be easily and quickly set up or taken down and may be used any number of times for shipping eggs or other material as the emptied crates can be folded and secured together before returned to the shipper.

Having thus described my invention, what I claim is:

1. A knock down box of the character set forth comprisin side and end Wall members, said side walls iaving their ends extending across and positioned against the side edges ofthe end walls, angled securing plates overlying the abutting edges of the end Walls and the adjacent side walls at each of the four sides of the box, that portion of each of the securing members lying against the end Walls, having arcuate slots formed therein and retaining pin members extending through the arcuate slots of each of said securing members and engaging the adjacent end wall for maintaining the securing members in slidable engagement with their respective end Wall members, said securing members when shifted in one direction being moved from contact With the adjacent side Wall members and when shifted in the opposite direction, being moved to frictional engagement with the adjacent side wall members to secure the side and end Walls together.

2. A knock down box of the character described, comprising side and end wall members, a pair of angled plate members at each side edge of each end wall, each iiieinbei of each pair having one portion thereof arranged against the outer face of the adjacent end Wall and provided with arcuate slots and the other portion thereof extending over the adjacent edge of the end wall to overlie the end of the adjacent side wall member, and securing elements extending through said slots into the adjacent end Wall to slidablv support the angled members thereon. said slots being so formed that when each pair of members is drawn together, the side overly ing portions thereof will be raised from contact with the box side wall members, the ieverse movement of the angled members causing the side overlying portions toy clamp the side wall members to the edge of the adja cent end wall. y

3. A knock down box of the character described, comprising side and end wall members, a pair of angled platevmembers at each side edge of each end wall, each member of each pair having one portion thereof arranged against the outer face of the adjacent end wall and provided with arcuate slots and the other port-ion thereof 'extending over the adjacent edge of the end wallto overlie the end of the adjacent side wall member, and securing elements extending through said slots into the adjacent end wall 'to slidably support the angled members thereon, said slots being so formed that when each pair of members is `drawn together, the side overlying portions thereof will be raised from contactyvith the box side wall members, the reverse move ment of the angled members causing the side overlying portions to clamp. the side wall members to the edge of the adjacent end Wall,

thereto, and resilient retaining elements positioned between the opposed ends of each pair of angled members and designed to normally maintain the angled members in sidewall sen curing position.

4. A knock down box of the character de-V scribed, comprising top, bottom, side and end wall members, shftable plate members carried by and having limited movement over a face of certain of said walls, and an engaging ably secured to a Wall member, the secured flange of each plate being so attached astoV cause the associate flange to move towards or away from the adjacent wall member when the plate is shift-ed.

In testimony whereof I alix my signature.
